Time-of-flight mass spectrometry for explosives trace detection
2012
This paper presents the ongoing development of a laser ionization mass spectrometric system to be applied for screening
for security related threat substances, specifically explosives. The system will be part of a larger security checkpoint
system developed and demonstrated within the FP7 project EFFISEC to aid border police and customs at outer border
checks. The laser ionization method of choice is SPI (single photon ionization), but the system also incorporates optional
functionalities such as a cold trap and/or a particle concentrator to facilitate detection of minute amounts of explosives.
The possibility of using jet-REMPI as a verification means is being scrutinized. Automated functionality and user
friendliness is also considered in the demo system development.
